Anal sphincter tears at vaginal delivery: risk factors and clinical outcome of primary repair.

OBJECTIVE To determine risk factors for obstetric anal sphincter tears and to evaluate symptomatic outcome of primary repair. METHODS Obstetric-procedure, maternal, and fetal data were registered in 845 consecutive vaginally delivered women. Risk factors for anal sphincter tears were calculated by multiple logistic regression. All 808 Swedish-speaking women who delivered vaginally were included in a questionnaire study regarding anal incontinence in relation to the delivery. Questionnaires were distributed within the first few days postpartum, and at 5 and 9 months postpartum. RESULTS Six percent of the women had a clinically detected sphincter tear at delivery. Sphincter tears were associated with nulliparity (odds ratio [OR] 9.8, 95% confidence interval [CI] 3.6, 26.2), postmaturity (OR 2.5, 95% CI 1.0, 6.2), fundal pressure (OR 4.6 95% CI 2.3, 7.9), midline episiotomy (OR 5.5 95% CI 1.4,18.7), and fetal weight in intervals of 250 g (OR 1.3 95% CI 1.1, 1.6). Fifty-four percent of women with repaired sphincter tears suffered from fecal or gas incontinence or both at 5 months and 41% at 9 months. Most of the symptoms were infrequent and mild. CONCLUSION Several risk factors for sphincter tear were identified. Sphincter tear at vaginal delivery is a serious complication, and it is frequently associated with anal incontinence. Special attention should be directed toward risk factors for this complication. Symptoms of anal incontinence should explicitly be sought at follow-up after delivery.

Anal incontinence after vaginal delivery: a prospective study in primiparous women

Objective To investigate the incidence and degree of anal incontinence after vaginal delivery among primiparous women and to define associated risk factors.

Anal incontinence after vaginal delivery: a five-year prospective cohort study.

OBJECTIVE: The long-term prevalence of anal incontinence after vaginal delivery is unknown. The aim of the present study was to evaluate the prevalence of anal incontinence in primiparous women 5 years after their first delivery and to evaluate the influence of subsequent childbirth. METHODS: A total of 349 nulliparous women were prospectively followed up with questionnaires before pregnancy, at 5 and 9 months, and 5 years after delivery. A total of 242 women completed all questionnaires. Women with sphincter tear at their first delivery were compared with women without such injury. Risk factors for development of anal incontinence were also analyzed. RESULTS: Anal incontinence increased significantly during the study period. Among women with sphincter tears, 44% reported anal incontinence at 9 months and 53% at 5 years (P = .002). Twenty-five percent of women without a sphincter tear reported anal incontinence at 9 months and 32% had symptoms at 5 years (P < .001). Risk factors for anal incontinence at 5 years were age (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.0–1.2), sphincter tear (OR 2.3; 95% CI 1.1–5.0), and subsequent childbirth (OR 2.4; 95% CI 1.1–5.6). As a predictor of anal incontinence at 5 years after the first delivery, anal incontinence at both 5 months (OR 3.8; 95% CI 2.0–7.3) and 9 months (OR 4.3; 95% CI 2.2–8.2) was identified. Among women with symptoms, the majority had infrequent incontinence to flatus, whereas fecal incontinence was rare. CONCLUSION: Anal incontinence among primiparous women increases over time and is affected by further childbirth. Anal incontinence at 9 months postpartum is an important predictor of persisting symptoms.

A three-year prospective assessment of rectocele repair using porcine xenograft.

OBJECTIVE: To prospectively evaluate clinical outcome of rectocele repair using xenograft 3 years after surgery. METHODS: Twenty-three patients who completed evaluation preoperatively and 1 year after surgery were assessed at a 3-year follow-up. Clinical examination was performed preoperatively, and at the 1- and 3-year follow-ups, with the pelvic organ prolapse quantification system. Symptom assessment was performed with a validated bowel function questionnaire including questions on sexual function. RESULTS: There were no graft-related complications during the 3 years following surgery. Preoperatively, all patients had stage II prolapse of the posterior vaginal wall and a rectocele verified at defecography. At the 1-year follow-up, 11 of 29 patients (38%) had rectocele of stage II or more, and 4 patients were reoperated. At 3-year follow-up 7 of 23 patients (30%) had rectocele of stage II or more. When including the 4 early anatomical recurrences, a total of 11 of 27 patients (41%) had rectocele of stage II or more at 3-year follow-up. Preoperatively, all patients reported varying degrees of rectal emptying difficulties and symptoms of bowel dysfunction. There was a significant decrease in rectal emptying difficulties (P < .01), sense of incomplete evacuation (P < .01), need for manually assisted defecation (P < .05), and symptoms of pelvic heaviness (P < .001) at the 3-year follow-up compared with preoperatively. Cure of rectal emptying difficulties was reported by fewer than 50% of patients. There were no significant changes in anal incontinence scores or symptoms of sexual dysfunction at the 3-year follow-up compared with preoperatively. CONCLUSION: Rectocele repair using porcine dermal graft was associated with an unsatisfactory anatomical cure rate and persistent bowel-emptying difficulties in the majority of patients 3 years postoperatively. LEVEL OF EVIDENCE: II-3

Risk of urinary incontinence after childbirth: a 10-year prospective cohort study.

OBJECTIVE: To estimate prospectively the effect of first delivery on subjective bladder function and to assess the influence of subsequent deliveries and obstetric events METHODS: We performed a prospective, observational cohort study. During a 10-week period in 1995, 304 of 309 eligible primiparous women (98%) entered the study at the postpartum maternity ward and completed a bladder function questionnaire. The 10-year observational period was completed by 246 of 304 subjects (81%). RESULTS: Prevalence of moderate-severe stress urinary incontinence increased from 5 of 304 subjects (2%) at baseline to 27 of 229 (12%) at 10 years follow-up (P<.001). Prevalence of moderate-severe urinary urgency increased from 0 subjects (0%) at baseline to 31 of 229 (13%) at the 10-year follow-up (P<.001). The relative risk (RR) (adjusted for maternal age and parity) of moderate to severe urinary incontinence increased significantly 10 years after first delivery (RR 5.8, 95% confidence interval [CI] 1.2–33.7). At multivariable analysis adjusted for age and parity, stress urinary incontinence symptoms at 9 months and 5 years follow-up were independently associated with the presence of symptoms at 10 years after index delivery (RR 13.3, 95% CI 3.9–33.1 and RR 14.1, 95% CI 2.5–18.8, respectively). Number of vaginal deliveries or other obstetric covariates did not affect the risk of stress urinary incontinence or urinary urgency. CONCLUSION: Vaginal delivery is independently associated with a significant long-term increase in stress urinary incontinence symptoms, as well as urinary urgency, regardless of maternal age or number of deliveries. LEVEL OF EVIDENCE: II-2

Obstetric sphincter tears and anal incontinence: an observational follow-up study

Background.  Persistent defects after primary sphincter repair and occult sphincter tears are common after vaginal deliveries. Anal incontinence may be associated with these morphological defects.

Functional and Anatomic Outcome After Transvaginal Rectocele Repair Using Collagen Mesh: A Prospective Study

PURPOSEThis study was designed to evaluate rectocele repair using collagen mesh.METHODS32 female patients underwent surgical repair using collagen mesh. Outcome was assessed in 29 patients and preoperative assessment included standardized questionnaire, clinical examination, and defecography. At the six-month follow-up, patients answered a standardized questionnaire and underwent clinical examination. At the 12-month follow-up, patients answered a standardized questionnaire, underwent clinical examination, and defecography.RESULTSPreoperatively, 26 patients had a Stage II and 3 patients had a Stage III rectocele. At the 6-month follow-up, five patients had rectocele ≥ Stage II (P < 0.001) and at the 12-month follow-up, seven patients had rectocele ≥ Stage II (P < 0.001) at clinical examination. At the preoperative defecography, all patients presented a rectocele. At the 12-month defecography, 14 patients had no rectocele (P < 0.001) and 15 had a rectocele. At the six-month follow-up, there was a significant decrease in rectal emptying difficulties, need of digital support of the posterior vaginal wall at defecation, and defecation frequency. At the 12-month follow-up, symptom improvement remained, but was less pronounced.CONCLUSIONSRectocele repair using collagen mesh improved anatomic support, but there is a substantial risk for recurrence with unsatisfactory anatomic and functional outcome one year after surgery. Rectocele repair using mesh was not associated with an increased risk of dyspareunia. Rectocele repair using biomaterial mesh reinforcement needs further evaluation before adopted into clinical practice.

Effect of hysterectomy on bowel function

Purpose: Hysterectomy is the most common major gynecologic procedure. Unwanted postoperative effects on bowel function are a topic of recent debate. The aim of the present study was to prospectively evaluate the influence of hysterectomy on bowel function. Methods: One hundred and twenty consecutive patients undergoing hysterectomy for benign conditions answered a questionnaire covering bowel habits and symptoms preoperatively and at 6 and 12 months postoperatively. Forty-four patients underwent vaginal hysterectomy and 76 underwent abdominal hysterectomy. Concomitant bilateral salpingo-oopherectomy was performed in 17 patients. Results: After abdominal hysterectomy, patients reported increased symptoms of gas incontinence, urge to defecate, and inability to distinguish between gas and feces (P < 0. 05). There was a tendency of increased fecal incontinence. Subgroup analysis indicated that concomitant bilateral salpingo-oopherectomy resulted in an increased risk of fecal incontinence. No significant changes were detected in symptoms associated with constipation. Mean defecation frequency increased and the frequency of pelvic heaviness symptoms was reduced. After vaginal hysterectomy, there was no increased frequency of incontinence or constipation symptoms. The frequency of pelvic heaviness symptoms was reduced. Conclusions: Patients undergoing abdominal hysterectomy may run an increased risk for developing mild to moderate anal incontinence postoperatively and this risk is increased by simultaneous bilateral salpingo-oopherectomy. An increased risk of anal incontience symptoms could not be identified in patients undergoing vaginal hysterectomy. Our study does not support the assumption that hysterectomy is associated with de novo or deteriorating constipation.

Durability of Success after Rectocele Repair

Abstract: The purpose of the study was to determine the durability of success after rectocele repair and to evaluate parameters that might influence long-term results. Twenty-five patients with rectocele were prospectively evaluated both clinically and physiologically. Follow-up was performed twice, at 1 and 5.1 years postoperatively. Twenty-four patients had a long-term follow-up; 21/23 patients (91%) with preoperative symptoms of rectal emptying difficulty reported improvement of their symptoms and 9 of 12 (75%) with preoperative symptoms of pelvic heaviness reported relief at long-term follow-up. All 5 patients with preoperative pathologic transit study had various degrees of rectal emptying difficulty at long-term follow-up. Three of 5 patients with preoperative paradoxical sphincter reaction (PSR) at electromyography (EMG) reported improvement of the symptoms of rectal emptying difficulty at long-term follow-up. Surgery for rectocele is associated with improved symptoms in a majority of patients which are sustained long term. Patients with pathologic transit study may have a less favorable symptomatic outcome. The clinical significance of PSR needs further study.

Effects of Hysterectomy on Bowel Function: A Three-Year, Prospective Cohort Study

PurposeThis study was a prospective evaluation of the long-term effects of hysterectomy on bowel function using self-reported outcome measures on symptoms of constipation, rectal emptying difficulties, and anal incontinence.MethodsIn this prospective cohort study, 120 consecutive patients undergoing hysterectomy for benign conditions answered a questionnaire on bowel habits and anorectal symptoms preoperatively. Forty-four patients underwent vaginal and 76 abdominal hysterectomy. Follow-up was performed one and three years postoperatively. Data were analyzed by using multivariate regression and nonparametric statistics.ResultsThe bowel and anorectal survey was answered by 115 of 120 patients (96 percent) after one year and 107 of 120 patients (89 percent) after three years. Abdominal hysterectomy was associated with increased anal incontinence symptoms at one-year (P < 0.01) and three-year follow-up (P < 0.01). Vaginal hysterectomy was not associated with increased anal incontinence symptoms at one year follow-up, although there was a significant increase in incontinence symptoms at the three-year follow-up (P < 0.05). Risk factor analysis indicated that a reported history of obstetric sphincter injury was correlated to an increased risk of developing posthysterectomy anal incontinence (odds ratio, 2.07; 95 percent confidence interval, 1.05–2.87; P < 0.05). There was no significant rise in constipation symptoms or rectal emptying difficulties in either cohort through the follow-up.ConclusionsNeither abdominal nor vaginal hysterectomy was associated with constipation, aggravation of constipation, or rectal emptying difficulties three years after surgery. Abdominal and vaginal hysterectomy was, however, associated with an increased risk of mild anal incontinence symptoms, and patients with a reported history of obstetric sphincter injury were at particular risk for posthysterectomy fecal incontinence.
